I used to live in Japan and around 50% of Japanese were sweet, friendly, welcoming and accommodating. 35% purposefully ignored or avoided me. And 15% were snide, bitter, racist, exclusionary, angry, rude assholes who can get fucked and/or need to go traveling to see that the world doesn't revolve around them. One of the sweet ones even shouted down, literally, one of the assholes who harassed me in the subway.
Come at me weebs. Except with "that's literally any country" bullshit. Japan is unique in this way.
